This Small Business Innovation Research Phase II project will demonstrate using a prototype design the commercial feasibility of electrospinning to produce nanofibers. Nanofibers will be combined with conventional filter media to form a novel NanoFilter media for liquid and air filtration applications. These applications have been shown to remove particles smaller than 3 microns from effluent streams with superior filtering efficiency and attractive cost potential. The acrylic nanofibers will be electrospun as a nanoweb directly on to a conventional support (filter media) substrate. The web will be combined with a protective cover layer to form a sandwich structure, which will be collected as a roll. The filter will be easily tailored to achieve the desired composite filter performance by varying architecture: substrates, nanofiber diameter, nanoweb density, and the nanoweb thickness. This project will be carried out collaboratively with academic centers and major corporations as its strategic partners. Nanotechnologies developed in the coming years will form the foundation for a significant commercial platform. Commercial applications in a variety of filtration processes such as: high-end industrial raw material purification, biological separations, ultra pure air and water systems, hospital clean rooms, agriculture and food industries filters, and microelectronic industries next generation clean environment needs are anticipated.

这个小企业创新研究第二阶段项目将使用原型设计来展示静电纺丝生产纳米纤维的商业可行性。纳米纤维将与传统的过滤介质相结合，形成一种新型的纳米过滤介质，用于液体和空气过滤应用。这些应用已经显示出以上级过滤效率和有吸引力的成本潜力从流出物流中去除小于3微米的颗粒。丙烯酸纳米纤维将作为静电纺丝直接在传统的支持（过滤介质）基板上。该幅材将与保护覆盖层组合以形成夹层结构，该夹层结构将被收集为卷。该过滤器将很容易定制，以实现所需的复合过滤器的性能，通过不同的架构：基板，纤维直径，纤维密度，和纤维厚度。该项目将与学术中心和主要企业作为战略合作伙伴共同开展。 未来几年开发的纳米技术将成为重要商业平台的基础。 预计在各种过滤过程中的商业应用，例如：高端工业原料净化，生物分离，超纯空气和水系统，医院洁净室，农业和食品工业过滤器以及微电子工业下一代清洁环境需求。
